Press-transferred carbon black electrodes coupled to microchip electrophoresis for food pesticides detection

In this work the assembling of novel carbon black (CB) press-transferred electrodes (CB-PTEs) is reported. The press-transferred nanomaterial based-approach presented may open new gates for electrochemical sensing since this technology does not require clean room facilities [1-2]. The electrodes have been designed to be coupled to microchip electrophoresis (ME) that gives excellent opportunities to carry out a quantitative multi-residual screening analysis characterized by rapidity, low sample and reagent consumption, and extremely low waste generation.
